Two grams of [(2,4-dichlorophenyl)phenylmethyl]malonaldehyde in 10 ml of ethanol were heated with 3 ml of anhydrous hydrazine on a steam bath for two hours. The reaction mixture was poured into water and extracted with ether. The ether extract was dried, filtered, and evaporated. The residue was crystallized twice from Skelley B/acetone to provide 1.2 g of the desired title product, m.p. 131° C.
